Prior to have scan on calf injury

Wicketkeeper Matt Prior was unable to take the field for England after suffering a tight left calf while batting, handing the gloves instead to Joe Root against Australia A.

Prior appeared to pull up short after Root called him for a quick single on day four at the Bellerive Oval.

After England then declared on 430 for seven, to give their bowlers some match action in the final session of this rain-wrecked fixture, Prior was not present.

Jonny Bairstow, Prior's wicketkeeping deputy for this Ashes tour, is the 12th man here - and first-class playing conditions stipulate he cannot take the gloves, unless a request is made and accepted for him to do so.

While the tourists therefore encountered an as yet minor injury hiccup, Australia published an encouraging update on one of their own.

All-rounder Shane Watson strained his hamstring in a one-day international against India a week ago.

Australian coach Darren Lehmann said: "The reports from our medical team on Shane's recovery from injury are pleasing.

"He is making good progress and responding well to treatment. If that continues, we have confidence that he will be fit for the first Test.

"We won't be taking any chances with his preparation, though, and he will miss next week's Shield match between New South Wales and Queensland at Allan Border Field.

"We want him to continue his treatment, and if all goes to plan join the Australian team in camp for the first Test in Brisbane."
